A quarter cylinder aquarium gravel calculator

Calculate amount of sand or gravel that is needed to attain a specific depth

in a quarter cylinder or corner bow front aquarium

The corner bow front aquariums are designed to fit in the corner of a room and to provide optimum viewing space. There is a quarter of a circle lies at the base of the aquarium with Radius (r). Calculate amount of sand, gravel or substrate required to attain a specific depth (h) in your corner bow front aquarium. Enter the aquarium base Radius (r), the required Gravel Depth (h), select unit of length measurement and gravel type, and press Calculate button to calculate how much gravel you need, in various units of weight measurement, to attain the specified gravel depth h. The number in square brackets, to the right of the gravel name, is the gravel specific gravity or relative density, as compared to pure water. See also our gravel calculators for cylindrical and rectangular shaped aquariums and ponds.

Gravel weight = (gravel density)× (gravel volume)

Gravel volumeV = π×r²×h ⁄ 4= 157.08

What is microgray?

Microgray is a derived metric (SI) measurement unit of absorbed radiation dose of ionizing radiation, e.g. X-rays. The SI prefix micro stands for one millionth. The microgray is equal to one millionth of a gray (10-6Gy), and the gray is defined as the absorption of one joule of ionizing radiation by one kilogram (1 J/kg) of matter, e.g. human tissue.read more...»
